命题 P11:II$_\infty$ factor + Fuglede–Kadison 行列式 = $\Xi(s)$

slug: ii_factor · verdict: weak-GO(仅作 P4+P10 子模块),NO-GO standalone · 难度: ★★★★★(circularity ⇔ RH)

§1 命题精确陈述

构造 II$_\infty$ factor $\mathcal M$ 与自伴 $D_{ar}$ affiliated to $\mathcal M$,使 Fuglede–Kadison 正则化行列式

$$\det^{FK}_\zeta(s-D_{ar}) = \Xi(s) = s(s-1)\pi^{-s/2}\Gamma(s/2)\zeta(s),$$

且 $D_{ar}$ 关于 canonical 半有限迹 $\tau$ 的 spectral measure = 非平凡 $\zeta$ 零点的 counting measure。这是非交换 Hilbert–Pólya 实现,subordinate to Weil 显式公式 (c) 子目标。

§2 L1 explorer 摘要

Sentinel — KILL(mpmath, $H=\frac12(xp+px)$ on $[0.5, 50]$ finite difference $N=500$, 前 100 eigenvalues vs $\zeta$-zero $\gamma_n$ + GUE 500×500 reference):

对象NN spacing variance
$H=xp$ truncated0.019(near-uniform Poisson-rigid)
$\zeta$ zeros0.204
GUE 500×5000.153

Counting up to $E=94.9$: $H=xp$ 给 99 levels (linear), ζ 给 27 levels (RvM $\frac{T}{2\pi}\log T$)。3.7× over-count 是 naive Hilbert space wrong by logarithmic factor 的 signature——任何 finite-dimensional / single-Hilbert-space truncation 不能恢复 ζ statistics;adelic limit 是结构必需而非便利。

L4 adversarial

(C1) Circularity — binding obstruction:Connes 1999 Thm III.1 distributional 恒等式 (无条件) ⇒ "Spec$(D_{ar})$ = $\{\gamma:\zeta(1/2+i\gamma)=0\}$ (real)" 等价 RH,不是 RH 的 consequence。Connes 自己 (1999 §VI 末尾) 写:"the validity of RH is equivalent to the self-adjointness of [the analogue of $D_{ar}$]"。BC 机器仅 deliver "easy direction":$D_{ar}$ self-adjoint affiliated to $\mathcal M$ + FK det $=\Xi$ ⇒ RH。Hard direction(构造 $D_{ar}$ self-adjoint without assuming zeros real)从未 close。Meyer 2005:BC 自然地把 zeros 给为非自伴 operator 的 cokernel,self-adjointness 正是 missing 的 RH-equivalent。

L5 verdict

§4 L4 panel

专家判定关键 reason

四 panel 一致:P11 不是 viable independent target;circularity 是 logical equivalence not soft worry。唯一 carve-off:FK-on-II$_\infty$ continuation lemma(C2)作 standalone operator-algebra 任务。

§5 最终 verdict 与建议

Final verdict: weak-GO(仅 P4+P10 sub-module),NO-GO standalone。$H=xp$ sentinel 确认无 finite-Hilbert-space shortcut;circularity 内 Connes BC 框架 maximally sharp(self-adjointness ⇔ RH);FK-II$_\infty$ analytic continuation 缺。demote to P4+P10 sub-module,carve off FK-II$_\infty$ continuation lemma 作 standalone operator-algebra 任务。
